Freenow had been showing a fare of 38.50 while we were flying and when I checked after passport control. We went to the pickup point and it showed 78! If figured it was a glitch, waited a few minutes and tried again. It went down to 70. Uber was 52 and we took that. FreeNow was still in the 60s as we headed off. A few minutes later it went back to 38.50 and was still there when I last checked 15 minutes later.
